1.0 System Description
The Lantronix 2-Port KVM (300.000.4000) is a Keyboard, Mouse and Video
switching system for one user and two PS/2-equipped computers.
2-Port KVM, Front View
1.1 System Features
• Control two computers with one Keyboard, Mouse and Monitor
• Emulates PS/2 Keyboard in the event of power interruption
• Front panel pushbutton controls AND keyboard control
• Front panel LEDs show connection status and power
2.0 Installation
The KVM 2-Port is connected in between two computers (or servers) and one
user station, consisting of a PS/2-type keyboard, PS/2-type mouse or trackball
device, and a video monitor. It must be placed within limited cable distances of
these components, but is generally placed on a shelf or in a 19-inch EIA
equipment rack near the computer equipment. The KVM 2-port requires one AC
power connection (an IEC-type power cordset is provided with the unit).
All connections are made with industry-standard mouse, keyboard and video
connectors found in conventional PC computer equipment. The necessary PS/2
and Video cables are ordered and shipped with the KVM 2-Port.

not press the front panel buttons to operate the unit.
There are no user-servicable parts inside the unit. A protective power fuse is

3.0 Operation
User Operation does not interfere with any mouse or keyboard activity of the
attached computers. There are two methods of operations: buttons and keyboard
control.
The front panel Power LED (to the left side) will show GREEN with normal
power. If the KVM 2-Port loses power, the Video signal will be lost.

3.1 Front Panel Button operation
The User can switch between Computer A and Computer B by pressing the
front panel button labeled 'A' or 'B'.
The front panel LEDs for A and B will show GREEN for the active computer, and
RED for the inactive computer.
The Video display may take a second to return, depending on the monitor used
and its internal switching capabilities.
3.1 Keyboard operation
The User can toggle between Computer A and Computer B by pressing and
releasing both 'Control' or 'CTRL' keys at the same time, on their PC-type PS/2
keyboard.
Note: This will not interfere with any computer operations or data.
The KVM 2-port will switch from one Computer to the other. The front panel
LEDs for Aand Bwill show GREEN for the active computer, and RED for the
inactive computer.
3.3 Keyboard Emulation
As long as the keyboard cables remain connected, the Keyboard connections will
be maintained with the attached servers, even in the event of a power failure to
the KVM 2-Port (this is important for some servers, which might reset if the
keyboard is disconnected).
The Keyboard connection to Computer A or B is maintained during a power
failure. When power is restored, the Video signal will become active again.
